Damaged Mathematic Systems Files, and Deleting Mathematica Caches?

Running Mathematica 3.0 on a Power Mac  8600 OS 8.1, I occasionally get
messages during operation saying that the file
"UnicodeShiftJISFontMapping.tr", buried deep in Mathematica:System
Files:Front End:Text Resources:, "could not be opened".  Operation then
continues OK.

I suppose that I could reinstall this one file, but I note that it (and
a lot of other Mathematica files) seem to be duplicated as .pbf in
"Cache" folders inside the main Mathematica folder.   Are these Cache
files critical?  Could they be corrupt?  Could deleting the Cache files
(a) free up any HD space, (b) force them to be regenerated?
